Customer Ratings & Reviews

When my dad’s car key battery died, these Energizer 2025 batteries were a total lifesaver! They were easy to install and worked perfectly right away. It’s great having a 4-pack, so we have extras on hand for the future. Definitely reliable and long-lasting, which is exactly what you want for something like this. Highly recommend for anyone who needs dependable coin batteries!

Excellent product last a long time happy about this purchase

Needed replacement batteries for our Samsung 3D glasses. Perfect fit. Also is the same size our kitchen food scale uses. Thank you Best Buy! Totally what we were looking for.

These batteries are so incredible. I am just speechless. Like I am so humbled by the privilege to own, not one, but TWO. TWO of these technologically super advanced mega power producers. I feel we should replace all the nuclear power plants in the world with just a few of these babies. What a time to be alive. Glory be to God.

These are the Best 2025BP-4 Batteries I have used! Highly recommend

Great for car key battery Hope will ladt long. Will update as i use.

Needed these for some candles we put in our window. They work great.

Very reliable batteries with a long shelf life and usage life

Needed new batteries for my car fob and these worked out perfectly!

Needed new batteries for my car's FOB and was able to order online from Best Buy and received them in 2 days. The price was good and I was able to use my Best Buy Reward Points for the purchase.

These batteries last a very long time, definitely impressed

Pretty good batteries, we use them for key fobs and garage door openers.

Worked well and took care of the needs. If you need 2025 batteries, these work well.

Batteries were a great value, and high quality! Needed them for a thermometer I keep in my house, but it was hard for me to find the batteries elsewhere...As soon as I got this pack I popped one into the thermometer and it came back to life. I have a feeling these new batteries will last a while!

Works great for my car key. Good quality batteries. They last a long time.

Great price for multiple batteries! So glad I found these in stock!

Energizer batteries are always our go to. They lasts long and never had any issue.

Wow, a request from Best Buy to review a Li-MnO2 battery... The C (Li) R (round) 2025 (20 mm diameter, 2.5 mm height) 3V (volts) battery has functioned exceptionally well during the two week period following the demise of its predecessor. It has neither suffered from the deleterious effects of rapid-discharge nor detonated. Li (lithium) metal (or an intercalation compound--Li is "captured" between the basal planes of graphite "LiC8") = anode (current enters, e^-1 leaves) MnO2 (manganese (IV) oxide) = cathode (e^-1 enters, current leaves) ***This is not to be confused with Thunderdome, i.e., two men enter, one man leave, even though many electrons flow prior to hearing the clap of thunder*** The Li cell is filled with an organic (Li metal reacts readily with water) solvent that: 1) does not react with Li metal (Li metal also readily reacts with, for example, carboxylic acids and alcohols: such a reaction in a sealed system would produce very energetic catastrophic failures as a result of a combination of pressure and the reactivity of H2 with O2), and, 2) allows for the dissolution of LiClO4 (lithium perchlorate). Its redox chem is rather straightforward in which; lithium is oxidized (0 to +1) and manganese is reduced (IV to III). Li <---> Li^+1 + e^-1 MnO2 + Li^+1 + e^-1 <--> LiMnO2 ------------------------------------------------- Li + MnO2 <--> LiMnO2 Oh, I only bought a four (4) pack because single (1) packs were not in stock. Thanks Best Buy! Now I have three (3) spare Li-MnO2 CR2025 3V batteries.

Had some old keyfobs for my car that stopped working and realized they needed new CR2025 batteries, and these were the only ones available at Bestbuy. Popped them in and the keyfobs were good as new again, and I fully expect them to last a long time given Energizer's reputation as a trustworthy battery brand.

Put these in my car key. Usually last at least a year, and that works for me!
